HORSESHOE.

SPECIFICATION forming part of Letters Patent No. 792,890, dated June 20, 1905.

Application filed November 10, 1904. Serial No. 232,166.

To all whom, it nuty concern:

Be it known that I, JOHN C. FLIGKINGER, a citizen of the United States, residing at Palmerton, in the county of Carbon and State of Pennsylvania, have invented a certain new and useful Horseshoe, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to horseshoes, and has for its object to provide a shoe and calks of such construction and arrangement that the calks may be readily and quickly applied to and removed from the shoe, the construction also enabling calks of different kinds to be easily interchanged, all of which may be accomplished without removing the shoe from the hoof of the animal.

The invention has particular reference to the means for fastening the calks in place relatively to the horseshoe, whereby the liability of displacement and loss of the calks is reduced to a minimum.

\Vith the above and other objects in view, the nature of which will more fully appear as the description proceeds, the invention consists in the novel construction, combination, and arrangement of parts, as herein fully described, illustrated, and claimed.

In the accompanying drawings, Figure 1 is a perspective view of a horseshoe with calks applied thereto in accordance with this invention. Fig. 2 is a horizontal section through one of the heel ends of the shoe, illustrating the means whereby the calks are fastened to the shoe. Fig. 3 is a detail perspective view of one calk. Fig. 4' is a similar view of another form of calk. Fig. 5 is a detail view of the pin or key.

Like reference-numerals designate corresponding parts in all figures of the drawings.

Referring to the drawings, 1 designates a horseshoe of ordinary form having toe and heel calks 2 and 3, respectively, applied thereto. The shoe is provided with thickened portions or ofi'sets 4 at the points where the calks are attached, as shown, to give the necessary strength and also form flat seats for the calks, which may be either of the sharpened or pointed form shown in Fig. l or of the flat or' blunt form, as shown in Fig. 4.

In carrying out the present invention each calk is provided with a stout shank 5, square or rectangular in cross-section, and the shoe is formed with correspondingly-shaped openings 6 to receive said shanks, whereby the calks are prevented from turning relatively to the shoe on which they are mounted. Holes 7 and 8 are formed transversely through the shank of each calk, said holes being located in the same horizontal plane and intersecting with each other, as shown in Fig. 2. The shoe 1 is also provided with a hole 9, extending transversely therethrough in line with the hole 7, so that a pin or key 10 may be inserted through the shoe and shank, as clearly shown in Fig. 2.

The pin or key 10 comprises a head 11, preferably made conical or tapering, so as to fit into one end of the hole 9, which is countersunk for the purpose. It also comprises a split or divided shank having twin spring portions or members 12 similar to an ordinary cotter-pin. The arms or members of the pin or key are flared apart at their extremities and are also offset about centrally of their length in opposite directions, as clearly shown, thus forming knobs or small lateral offsets or projections 13, which as the pin is inserted through the shoe and calk-shank spring outward or away from each other, and enter and engage the notches or seats formed by the intersection of the holes 7 and 8, thus preventing the accidental escape of the pin or key, while permitting it to be Withdrawn by proper manipulation on the part of the operator. The other end of the hole 9 is also flared to allow theextremities of the pin to be bent apart and clenchedlike a cotter-pin and to serve as an additional fastening for the device.

By means of the construction above described calks may be readily applied to and removed from a horseshoe in an expeditious manner, thus allowing a set of calks of one character to be quickly interchanged with calks of another kind without removing the shoe from the hoof.

Having thus described the invention, What I claim as new, and desire to secure by Letters Patent, isl 1. A horseshoe provided with an opening and a pin-hole leading thereto, a calk having a shank fitting said opening and provided with intersecting holes at an angle to each other, and a spring key or pin inserted through the hole in the shoe and into one of the holes in the shank and provided with knobs or projections which engage in the notches formed by the intersection of the pin-holes in the shank.

2. A calk for horseshoes,ennbodying a shank extending at an angle to the head of the calk and provided with intersecting holes extending substantially at right angles to each other.

In testimony whereof I alfix my signature in presence of two witnesses.

JOHN C. FLIOKINGER.
